Introduction
Filamentary keratitis can be managed by removing the localized filaments and applying antibiotic eye ointment. The patient’s primary symptoms include epiphora (excessive tearing), photophobia, and a foreign-body sensation in the eye; notably, this foreign-body sensation intensifies significantly with blinking. Slit-lamp examination reveals curled, filamentous strands within the corneal epithelium, allowing for a definitive diagnosis. Appropriate use of topical antibiotic eye drops and ointment is recommended to prevent secondary infection.

Filamentary keratitis refers to a condition characterized by curled, thread-like filaments on the corneal surface, resulting from partial detachment of the corneal epithelium. One end of the detached epithelial strand remains adherent to the cornea, while the other end floats freely—resembling fine silk threads, hence the name “filamentary keratitis.” So, how is filamentary keratitis treated?

How Is Filamentary Keratitis Treated?

Filamentary keratitis can be managed by carefully removing the local filaments and applying topical antibiotic ointment. The primary symptoms experienced by patients include epiphora (excessive tearing), photophobia (light sensitivity), and a foreign-body sensation in the eye; notably, this sensation intensifies significantly with blinking. Slit-lamp examination reveals curled, fine filaments within the corneal epithelium, allowing for a definitive diagnosis. Appropriate topical antibiotic eye drops and ointments are prescribed to prevent secondary infection. Additionally, corneal epithelial nutritional agents and oral vitamin supplements may be recommended. A 10% acetylcysteine solution can reduce filament adhesiveness, facilitating easier removal of the curled filaments. Topical hyperosmotic agents are also effective in treatment. Following corneal epithelial debridement, wearing soft contact lenses may help alleviate symptoms, and preservative-free artificial tears can be used locally.

To prevent keratitis, avoid excessive eye strain and fatigue. During the day, limit prolonged exposure to computer screens, smartphones, and other electronic displays. Avoid reading in dimly lit environments. At night, go to bed early and avoid staying up late, as sleep deprivation compromises ocular immunity and increases susceptibility to keratitis.

In daily life, cultivate healthy lifestyle and dietary habits. We hope this information proves helpful to you.
